FIG 02 · Quick answer
What is HR software development?
HR software development is building the systems that manage employee records, hiring, onboarding, time, leave and payroll data. Elgrith builds custom HRMS modules and HR-tech products, and integrates them with Workday, BambooHR or your payroll provider, with I-9, UK right-to-work and overtime rules modelled in from the start.
- Hiring, onboarding, time, leave and payroll data in one employee record
- Hire → payroll
- Projects delivered since 2015
- 1,000+
- Clients across the USA, UK and India
- 250+
- Your code, repository and IP
- 100%
FIG 03 · Why it matters
Employment law has already written part of your data model.
From USCIS, the US Department of Labor and GOV.UK, read on 23 Oct 2026.
01
01/20/25
Current Form I-9 edition
USCIS lists the 01/20/25 edition of Form I-9. Employers keep each form for three years after the date of hire, or one year after employment ends, whichever is later.

40
Hours before FLSA overtime
Covered non-exempt US employees must get overtime for hours over 40 in a workweek at not less than time and one-half their regular rate, says the Department of Labor.

UK unfair dismissal qualifying period cut to six months
GOV.UK’s Employment Rights Act timeline (updated 22 Oct 2026) cuts the qualifying period to six months for dismissals from 1 January 2027. It notes future dates may change.

FIG 04 · HRIS, HRMS, HCM
HRMS software development: modules and data model
Vendors use these three terms loosely. This is how we use them when we scope HRMS software development with you, so everyone means the same thing.
| HRIS | HRMS | HCM | |
|---|---|---|---|
| Core job | The system of record for employee data | HRIS plus the processes: time, leave, payroll data, onboarding | HRMS plus talent: recruiting, performance, learning, planning |
| Typical modules | Employee records, org chart, documents | Time and attendance, PTO, onboarding, self-service, payroll inputs | ATS, reviews, goals, compensation, workforce planning |
| Who it serves | HR admins | HR, managers and every employee | HR, leaders and talent teams |
| Where custom fits | Records your vendor can’t model | Leave, shift or overtime rules no product fits | A talent product you sell, or a flow that sets you apart |
Under every module: role-based access, an audit log, SSO and SCIM provisioning, and retention rules per record type.

FIG 06 · Integrations
Integrations with Workday, BambooHR, ADP and payroll
Most employers keep their HRIS or payroll and need what is missing around it. We integrate through each vendor’s published APIs, under your agreement and your access. We claim no partner status with Workday, BambooHR, ADP or any HR vendor.
- HRIS
- Applicant tracking
- Time clocks
- Payroll
- Accounting
- SSO and identity
Workday
- What we build
- Apps and data flows that read and write workers, jobs and time through Workday’s published APIs
- What stays
- Your Workday tenant and configuration; we don’t resell or re-platform it
BambooHR
- What we build
- Onboarding, time and reporting tools on top of BambooHR employee data
- How
- BambooHR’s API and webhooks, with your API access
ADP and payroll providers
- Data
- New hires, pay changes, hours, leave and deductions sent to payroll; payslip data back
- How
- APIs only, under your payroll agreement; no screen-scraping
HR Open Standards
- What it is
- An independent non-profit publishing HR data-exchange specifications
- Where
- Data models and messages between HR systems, where your partners use them
Accounting
- Data
- Payroll journals, cost centres and accruals
- Where
- Your accounting system’s API
Everything else
- Examples
- Benefits platforms, background checks, e-signature and learning tools
- Approach
- One API layer, so a vendor change doesn’t break HR
FIG 07 · Hiring
Recruiting and ATS features
Recruitment software development is about speed without losing the paper trail: every candidate, stage and decision recorded.
05principles
Job posts
Openings published to your careers page and job boards from one place.
Pipelines
Stages, scorecards and feedback per role, with candidates moving through on clear rules.
Interview scheduling
Calendar links, panels and reminders without the email ping-pong.
Offers
Offer letters from approved templates, e-signed, then handed to onboarding with no re-keying.
AI screening with human review
AI can summarise and sort applications; a person makes every decision, and the criteria are recorded.
AI development
FIG 08 · Rules
Rules your HR system has to hold
The rules change by country, and they change by date. We model them as data your HR team can update, not code. General guidance from public sources, not legal advice; your counsel confirms what applies to you.
05principles
Form I-9 and E-Verify (US)
I-9 records on the current edition, with retention dates calculated from hire and leave dates. E-Verify cases stay in E-Verify; we store the case status your process produces.
FLSA overtime (US)
Exempt and non-exempt status on every job, and hours over 40 in a workweek flagged for overtime at time and a half.
Right to work (UK)
Right-to-work check records kept as the Home Office employer’s guide (updated 1 Oct 2026) describes, with follow-up dates for time-limited permission.
Employment Rights Act (UK)
Sick pay from day one since 6 Apr 2026, a six-month unfair dismissal qualifying period from 1 Jan 2027, and new flexible working rules from Oct 2027.
Labour Codes (India)
Four Labour Codes in effect since 21 Nov 2025, replacing 29 labour laws. Rules under them are still being framed, so wage and contribution logic stays configurable.
FIG 09 · Payroll data
Payroll software development, designed to support your provider
Most employers should keep a payroll provider and send it clean data. Where you need your own calculations, we build them designed to support the rules, with your payroll provider or accountant confirming every rate.
04principles
Gross-to-net inputs
Hours, overtime, allowances, deductions and leave, validated before they leave HR.
Rates as data
Tax, contribution and overtime rates stored as dated tables your accountant can check and update.
Provider exports
Payroll files or API calls in the format your provider expects, with a reconciliation report back.
Effective dating
Every pay change stored with its date, so back pay and audits come from the record, not memory.
FIG 10 · Security
Security for employee data
HR systems hold bank details, IDs, health notes and salaries. We design for least privilege from the first screen.
06principles
Encryption
Data encrypted in transit and at rest, with sensitive fields like bank and ID numbers encrypted separately.
Least privilege
Role-based access by job, team and location; managers see their team, not the company.
Audit log
Every view of and change to sensitive data recorded, for your own reviews and investigations.
SSO and SCIM
Sign-in through your identity provider, with accounts created and removed automatically.
Retention schedules
Records deleted or anonymised on dates your HR and legal teams set, per record type and country.

FIG 16 · Choosing a vendor
What to check before you hire an HR software development company
Choosing an HR software development company? These are the questions we’d ask any vendor, including us.
| Question | Why it matters | Our answer |
|---|---|---|
| Who owns the code and data? | Employee data is yours and must stay portable | You do: code, repository, data and IP are assigned to you |
| How are rules changed? | Leave, overtime and pay rules change by date and country | Rules stored as dated data your HR team can update |
| How is access controlled? | Salaries and IDs are the most sensitive data you hold | Role-based access, audit log, SSO and SCIM by default |
| Which integrations are real? | Some vendors promise connectors they don’t have | Published APIs only, under your agreements; no partner claims |
| Who confirms the law? | Software can’t give legal or tax advice | Your counsel and payroll provider; we build what they confirm |
We don’t publish prices or timelines: both are agreed in your written scope after a free call.

Frequently asked questions
Straight answers about HR Software Development with Elgrith.
We don’t publish prices, because cost depends on scope: which modules (core HR, onboarding, time, leave, ATS, payroll data), how many countries and policies, which integrations, whether you need a mobile app, and how much data must move. After a free call you get a written scope and a fixed quote.
